First, select the LOWEST magnification eyepiece! That will give you the widest field of view.

Next, check the alignment of your finderscope by looking at a distant object on the horizon, like a light at the top of a tower, or any distant fixed object. Center the object in the telescope's field of view, then adjust the finder so that it's centered there, too. You can do this either in the daytime or at night.

With the finderscope aligned and the lowest power eyepiece, finding your object should be a snap. Once you've got the object with the low power eyepiece, center it again and you can go to higher power if you want.

If I had to take a wild guess, I'd say you are probably using a cheap telescope, but here is what to do.

1. Make sure the cap is off the telescope.
2. Put in the lowest powered eyepiece you have...this is the one with the higher number in mm. For example, a 25mm eyepiece is lower magnification than a 10mm eyepiece.

3. Point the telescope at a large but distant stationary object. It's best to use something here on Earth but the moon will work sometimes. Make sure you can see the object in the telescope.

4. The viewfinder should have three adjustment screws on it. Turn two of these so that the viewfinder is looking at the same thing the telescope is. Use the third screw to make the final adjustment....it's easiest to use any two of them until you have to use the other.

5. Repeat this processes using higher magnification eyepieces until the view finder and telescope are looking at exactly the same thing.

6. Put the lower powered eyepiece back in and using the view finder, point the telescope at what you want to look at.

7. Looking through the eyepiece, slowly turn the focus knob until the image focuses.

With a 60 mm telescope, Venus should be very bright in the viewfinder. I presume that you can see Venus in the dark sky with the naked eye and you know where to point your telescope.

Try to test the telescope in daylight. Make sure that you are able to focus it on a distant terrestrial object. The object will be inverted in the viewfinder, but that is normal.

I presume that you have a 60mm diameter objective on a refractor telescope. If you are using a reflector, it is possible that the main mirror, the secondary mirror and the viewfinder do not align.

Again, as with the refractor, check the reflector out on land on a distant object.

Good luck.

Before doing anything, adjust your view finder (also known as a finder scope) using a bright star high in the sky to line it up with the middle of your view in the scope. Then you can use the view finder to find Venus and look at it. Venus will look like phases of the Moon. At its brightest it is somewhere around a 1/4 moon or so.

You need to focus your scope if you don't see stars. Try looking at distant mountains or trees during the day time for practice. NEVER LOOK AT THE SUN. You can damage your eyes.

venus only appears right when the sun is halfway set and halfway risen.
